Is Skype free on iPhone 4?

Yup! It's free. You will use data when you download the app if you are not on a wi-fi connection at the time.

You can use the video call feature on your iPhone 4 on when connected to wi-fi, it's awesome though! Tango and Facetime are cool as well.

Have fun!

Do sim cards work for any phone?

SIM cards do not always work for any cell phone, as most wireless providers lock their phones to their specific network. Putting a SIM card into a cell phone locked to a different company usually triggers a service provider lock. Usually, the only way to get around this is getting the unlock code from the wireless provider it was originally used with, which they may not allow. In addition, some cell phones, usually CDMA, do not even have a slot for a SIM card.

What is the answer to level 35 for fill the pot in logic game box?

This one took me forever...just figured it out. Wish I could post a picture.

The two tall #3 pots go under the left and right #3 pipes.

The long #3 pot goes on top of the #4 pot to the very left and the #2 pot goes under the #2 pipe on the right, but the bottom has to touch the bottom square.

Starting with the #1 pipe on the left attatch the vertical pipe and the pipe that curves down and to the right, pouring water into the #3 pot.

To the middle #3 pipe attatch the pipe that curves down and to the right, then to the right and down, then down and to right again, pouring water into the #4 pot.

To the #1 pipe on the right attatch a pipe that curves down and to the right, pouriing water into the #4 pot.

To the #2 pipe on the left attatch the remaining pipe that curves down and to the right, pouring water into the #2 pot.

And to the #2 pipe on the right attatch the pipe that curves down and to the left and then the horizontal one pouring water into the long #3 pot.

Hope this makes sense and helps anyone else who is stuck on this level!

How do you unlock an iPhone 4 BB 04.12.09 with superior sim Ultra full guide here?

Review: Superior Sim Ultra + For iPhone 4 Modemfirmware 04.12.09 with Ios 7.0.4 SIM hack

For much of the last two years time, even the manufacturer of these SIM hack products acknowledge that their product is no longer needed; so it was quite a surprise when Superior Solution announced that they have something that will unlock the iPhone 4 BB 04.12.09 with Ios 7.0.4 . Contrary to conspiracy theories, they withheld onto the product because:

  • Initial production cost is high, they risk losing a lot of their investment should the dev team come up with a software unlock that does the same job if not better, before they were able to recover their cost.
  • The exploit they used is not without serious problems, hence they were reluctant to produce it until there seems to be no alternatives coming for a while.
  • The exploit they used is very simple, provided you have the tools and skill, details to follow...

I have made a mistake earlier by calling it TurboSIM and it is not. @MuscleNerd reminded me of the correct term "SIM interposer", since it sits electrically between the SIM card and baseband hardware to perform a classic.

How did It Work?

SIM card holds many different types of information, but the part most involved with carrier lock is the IMSI number, which is a unique code that corresponds to your account in the mobile carrier's database.

A sample IMSI might look like this

310 150 987654321

The first two segments are known as Mobile Country Code (MCC) and Mobile Network Code (MNC) respectively, and in the example above the IMSI indicate the SIM is from USA (310) AT&T (150).

When the iPhone baseband is loaded into memory, it checks the MCC and MNC against its own network lock state stored in the seczone. If the combination is allowed, the cell radio is activated and vice versa.

The earliest iPhone baseband revisions only check IMSI twice following a restart, therefore it is very easy to spoof information in order to bypass the check. Never theless, the baseband was soon updated to validate SIM more aggressively and the method no longer works.

To guard against eavesdropping that plagued pre-GSM cellular networks, the initial connection to a network does not only involve IMSI, but a 4-byte TMSI to identify each handset before IMSI is sent. The base station recognises the IMSI as one of their users and replies with a nonce (RAND) to the handset, where is signed with a 128bit key (Ki, stored encrypted on the SIM) and sent back. The network checks the string against their own result using the same RAND and Ki and allows the device to register if the two value matches.

You see, the IMSI is only sent once and never directly involved with authentication; as long as your key is valid, you will be able to get service. This is exactly what the various SIM hacks where a fake IMSI is sent along with the correct key. In our case, the IMSI is invalid but some network proceed to the next step anyway - I will explain this in detail later.

Partial Revival

Apparently somebody figured out that while the i4 baseband has been patched to prevent test IMSI from working, it is still possible to force activate the baseband using the emergency dialer.

After that, it is relatively the same trick all over again. Let's see what it does at each step.

You will need to use the SIM tray supplied and file your MicroSIM slightly to accommodate the EEPROM chip.

Installing the Superior Sim Ultra +.

The phone will search for signal, comes up with no service and finally settling on this "one bar" icon. At this stage the sim interposer is passing the parameters from the SIM as is.

Dial 112 and hang up after the call is connected. The emergency call overrides the network lock and activates the cell radio. The network issues a TMSI for your real IMSI.

Note: This Step No Appear Normally This step When I Do When I Not Got Sinals In Bars.

Toggle Airplane mod On/Off. Once the interposer senses Airplane mod, it transiently blocks electrical connection between the phone and the SIM (hence it will show "No SIM card installed")

The signal bars appear, we are safe:-) The network is able to register you again because the TMSI you obtained earlier is still valid, and the IMSI is not checked again.

How many songs can iphone 4 hold?

I think it's about 1,000 songs. It all depends on the firmware you have installed. Firmware 1.1.* will hold more than 2.* due to the simple fact that as firmware is updated, more storage is needed for the OS it self. Its like Windows. XP only required about 1.5GB and now Vista is pushing 10GB more functionality = less free space for you.
